1. India’s Hypersonic Leap: DRDO Tests Actively Cooled Scramjet | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-3: Science and Technology (Indigenization of Technology & Defence)
Why in News? The Defence Research and Development Organisation (DRDO) has successfully conducted a long-duration ground test of an Actively Cooled Scramjet Full Scale Combustor. This is a pivotal step towards developing India’s indigenous hypersonic cruise missiles.

Deep Dive: Understanding the Technology
- What is a Scramjet? A Supersonic Combustion Ramjet (Scramjet) is an improvement over the Ramjet engine. In a Ramjet, the air is slowed down to subsonic speeds before combustion. In a Scramjet, the airflow remains supersonic throughout the engine. This allows the vehicle to fly at speeds exceeding Mach 5 (hypersonic speeds).
- The “Active Cooling” Breakthrough: One of the biggest challenges in hypersonic flight is the extreme heat generated by air friction and combustion, which can melt the engine. Active Cooling uses the fuel itself as a coolant. The fuel circulates through channels around the combustion chamber to absorb heat before being injected for combustion. This prevents the engine from overheating during long-duration flights.
- Significance for India:
- Strategic Deterrence: Hypersonic missiles are harder to detect and intercept due to their speed and low-altitude flight paths compared to ballistic missiles.
- Elite Club: Only the US, Russia, and China have mature hypersonic capabilities. This test cements India’s position in this elite group.
- HSTDV Link: This test builds upon the success of the Hypersonic Technology Demonstrator Vehicle (HSTDV) test conducted in 2020.
Key Points:
- The test validated the sustained combustion capability, which is critical for long-range missiles.
- The technology will likely power India’s future Hypersonic Cruise Missile (HCM).
- The test was conducted at DRDO’s propulsion test facility in Hyderabad.
Prelims Practice: Consider the following statements regarding Jet Engines:
- A Ramjet engine can operate efficiently at zero airspeed (static).
- In a Scramjet engine, combustion takes place at supersonic airflow speeds.
- Active cooling in scramjets often uses the fuel as a coolant.
Which of the statements given above is/are correct? (a) 1 only | (b) 1 and 2 only | (c) 2 and 3 only | (d) 1, 2 and 3 Answer: (c) (Ramjets/Scramjets cannot start from zero airspeed; they need an initial boost).
2. The Shaksgam Valley Issue : India Rejects China-Pakistan Border Agreement | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-2: International Relations (India & Neighbourhood Relations)
Why in News? Ministry of External Affairs of India has strongly reiterated its rejection of the 1963 China-Pakistan Boundary Agreement, asserting its sovereignty over the Shaksgam Valley in response to recent infrastructure developments by China in the region.
Deep Dive: The Geopolitics of Shaksgam
- Geography: The Shaksgam Valley (Trans-Karakoram Tract) lies north of the Karakoram range, covering approximately 5,180 sq km. It connects Pakistan-Occupied Kashmir (Gilgit-Baltistan) with China’s Xinjiang province.
- The 1963 Agreement: Pakistan ceded this territory to China in 1963. India has never recognized this “Boundary Agreement” because Pakistan has no legal standing to cede territory that belongs to the Indian state of Jammu & Kashmir (now UT of Ladakh).
- Article 6 Flaw: The 1963 agreement contains a clause stating that the border would be renegotiated after the Kashmir dispute is settled, proving the arrangement was “provisional.”
- Strategic Threat:
- Siachen Encirclement: The valley lies to the north of the Siachen Glacier. Chinese presence here, combined with Pakistan’s presence in the west, creates a “pincer” threat to Indian positions in Siachen and the Sub-Sector North (SSN) in Ladakh.
- CPEC Link: The valley is close to the route of the China-Pakistan Economic Corridor (CPEC).
Mains Question: “The Shaksgam Valley dispute is not merely a territorial issue but a strategic fulcrum in the China-Pakistan-India triad.” Critically analyze India’s consistent stance on the 1963 China-Pakistan Boundary Agreement and its implications for national security.
3. India-EU FTA: Navigating the ‘Rules-Based’ Trade Maze | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-2: International Relations (Bilateral Agreements) & GS-3: Economy
Why in News? High-level talks between India and the European Union (EU) resumed in Brussels, aiming to finalize the ambitious Free Trade Agreement (FTA).
Key Analysis
- The “BTIA” Legacy: Negotiations originally began in 2007 as the Broad-based Trade and Investment Agreement (BTIA) but stalled in 2013. They were relaunched in 2022.
- Key Sticking Points:
- CBAM (Carbon Border Adjustment Mechanism): The EU’s “Carbon Tax” on steel, cement, and aluminum is a major concern for India. India views this as a non-tariff barrier.
- Market Access: The EU wants lower duties on automobiles, wines, and spirits. India protects these sectors to safeguard domestic manufacturers.
- Sustainability Clauses: The EU insists on including strict labor and environment standards, which India argues should not be linked to trade.
- India’s Interests:
- Greater access for textiles, leather, and pharmaceuticals.
- Service Sector: Easier visa norms for Indian IT professionals (Mode 4 of services trade).
- Geographical Indications (GIs): Protecting Indian products like Basmati rice.
4. UN WESP 2026: Economic Headwinds & Resilience | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-3: Indian Economy (Growth & Development)
Why in News? The UN’s World Economic Situation and Prospects (WESP) 2026 report has projected India’s growth at 6.6% for 2026, a moderation from the 7.2% – 7.4% estimated for the previous year.
Key Analysis
- Why the Moderation?
- Global Slowdown: The report cites a global economic cooling due to high interest rates in developed economies and geopolitical tensions (Red Sea crisis, Ukraine).
- Base Effect: Coming off a high growth base in FY25 naturally leads to a statistical moderation.
- The Silver Lining: Despite the moderation, India remains the fastest-growing major economy. The report highlights strong domestic demand and public infrastructure investment (Capex) as the twin pillars shielding India from global volatility.
- UN vs. Others: The UN’s projection is often more conservative than the IMF or World Bank. This signals a need for cautious optimism.
Prelims Practice: The ‘World Economic Situation and Prospects’ report is jointly released by: (a) World Bank & IMF (b) World Economic Forum (WEF) (c) UN-DESA, UNCTAD & UN Regional Commissions(d) WTO & OECD Answer: (c)
5. Road Safety 2.0: New Norms for Sleeper Buses | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-3: Infrastructure (Roads) & GS-2: Governance
Why in News? Union Minister Nitin Gadkari has announced mandatory safety features for sleeper buses, following a spate of tragic accidents involving fire and entrapment. You can visit the official site of Ministry of Road Transport and Highways (MoRTH) by clicking the link for information.
Key Mandates
- Fire Detection & Suppression System (FDSS): Must be installed in the passenger compartment, not just the engine bay.
- Emergency Exits: Redesigned exits that are easily accessible from sleeper berths.
- Driver Drowsiness Detection: AI-based cameras in the cabin to alert the driver if they close their eyes or look away from the road for too long.
- Material Safety: Use of fire-retardant materials for upholstery to prevent rapid fire spread.
Significance: Sleeper buses are popular for long-distance travel in India but have been termed “moving coffins” due to poor design. These norms aim to align Indian buses with global safety standards.
6. Bharat’s AI Leap: The Push for ‘Sovereign AI’ | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-3: Science & Tech (AI & Awareness in IT)
Why in News? Prime Minister Modi has advocated for an Indigenous AI Model, emphasizing that India needs “Sovereign AI” that respects its linguistic diversity.
Deep Dive: Why Indigenous AI?
- Data Bias: Global models (like GPT-4) are trained primarily on English and Western data. They often fail to capture Indian cultural nuances or regional languages.
- Bhashini Platform: The government’s National Language Translation Mission (Bhashini) is the backbone of this initiative. It aims to collect datasets in Indian languages to train AI models.
- Strategic Autonomy: Relying on foreign AI models for critical governance (e.g., land records, legal advice) poses data privacy and security risks.
- Example Case: The “Kumbh Sah’AI’yak” bot used during the 2025 Maha Kumbh (mentioned in recent retrospectives) demonstrated how AI can serve millions in local dialects. (Tip- Note this down to use an Example in GS-3 and case studies related to AI)
7. Internal Security: NIDMS & NCORD | UPSC Current Affairs 10 Jan 2026
Syllabus Mapping: GS-3: Internal Security (Terrorism & Organized Crime)
Why in News? Home Minister Amit Shah inaugurated the National IED Data Management System (NIDMS) and chaired the 9th NCORD meeting.
Key Analysis
- NIDMS (National IED Data Management System):
- Agency: Developed by the National Bomb Data Centre (NBDC) of the NSG.
- Function: A centralized digital database of all IED (Improvised Explosive Device) blasts, designs, and signatures found in India.
- Goal: To help investigators link disparate attacks to specific terror groups based on “bomb signatures.”
- NCORD (Narco Coordination Centre):
- The Threat: Narco-terrorism (using drug money to fund terror).
- Structure: It is a 4-tier mechanism (Apex, Executive, State, District) to ensure better coordination between central agencies (NCB) and state police.
- Outcome: The meeting emphasized a “Whole of Government” approach to destroy the drug supply chain from “Source to Destination.”
